CELL C IS THE WORST COMANY TO DEAL WITH

I am with cell c for over 10 years. 1 year ago I was due for an upgrade. after many marketing smses and telephone calls from cell c, asking me to ugrade, I decided to upgrade, from then the experience with cell c was disgusting and appalling. cell c gave me a second hand Samsung A50. while using it the security pattern was not working. I took the phone back within the 7 day period, in the centurion mall, the manager also confirmed that there was problems with the A50, and that I am not the only client. and she booked it iin, the repairs department **** and said it was a software update issue. mind u I did software update the repairs department returned the phone back to the store. the manager picked up that they didn't do a software upgrade but changed the screen and **** that the issue was the software update,. the phone came back to the store with scratches. The manager (Thembi) booked the phone again,she said that they changed the screen and that if I take the phone I am going to have further problems as it is not the original screen. cell c still debited my account and I still don't have a phone. I tried calling head office many times for help but they kept on putting me to different departments. till now I have no feedback as to whats going on. I wish I never took out the contact from cellc . this is the worst company out there. please be carefull when signing up with cell c. you will regret it. the amount of run arounds.
